Police said Sunday that the same man is believed to be responsible for four armed robberies between Jun. 8 and Sunday.

The first happened June 8 about 11:40 p.m. in the 2600 block of Burgundy Street. The second incident happened June 13 about 1:45 a.m. near the intersection of Mandeville and N. Rampart streets. The third happened about two hours later, about 4 a.m., in the 1400 block of Bourbon Street at the edge of the French Quarter and Marigny neighborhoods. The fourth incident happened about 2:45 a.m. June 15 in the 1200 block of Burgundy Street.

WDSU confirmed Monday that detectives also believe the suspect and an accomplice committed two armed robberies in the 1000 block of Governor Nicholls Street two weeks ago.

Police released a composite sketch of the man they believe is responsible for the robberies. Surveillance video was also released by the NOPD of the Bourbon Street incident.

Police believe the man is between 17 and 25 years old. In the surveillance video, the suspect can be seen firing a gun into the air. Victims told police that the suspect was carrying a semi-automatic hand gun.

Police said they tied the subject in the surveillance video to the other robberies after matching a composite sketch from the other scenes.

No further information was made available.
